Incorrect Question 6 Which reservoirs have lost carbon since pre-industrial times (assume the uncertainties are all zero)? Ocean floor sediments Permafrost Volcanoes Vegetation ✔Intermediate and Deep Sea Fossil fuel reserves 0/2 pts Atmosphere
Incorrect Question 7 0/2 pts By what percent of its natural value has the flux of carbon into the ocean from the atmosphere (not the net flux) increased? Round to the nearest whole percent and input a number only. 11
